| General Information: | |
This high-performance switch uses LACP and IEEE 1588v2 to optimize network operations. LACP is used in high-availability and performance environments, such as data centers or enterprise networks, to aggregate links between switches, servers, or routers. It simplifies management by treating multiple links as one, and improves resilience by avoiding single points of failure. LACP scales network capacity without upgrading individual links. IEEE 1588v2, also known as Precision Time Protocol (PTP), is a standard protocol used to precisely synchronize clocks across a network. This is important in applications that require highly accurate timing, such as telecommunications, industrial automation, power systems, and financial services. Fully manageable The switch is fully managed, supporting SNMP version 1, 2c, and 3. The embedded RMON software agents support RMON groups 1 (history), 2 (statistics), 3 (alarms), and 9 (events). The integral Web server enables Web-based management via a Web browser. This GUI interface enables switch configuration, system dashboard, maintenance, and monitoring, and includes a wide range of management and support features. Support for VLAN and QoS Support for up to four simultaneous VLANs segments traffic with port-based, 802.1Q tag-based, or MAC-based VLANs. 802.1p Layer 2 quality of service (QoS) prioritizes time-sensitive applications such as VoIP and video. Secure Enterprise-class security features include 802.1X port-based network access control to authenticate devices connecting to your network. The switch also supports SNMPv3 cryptographic security, SSH, and SSL. Plus, you can set up a guest VLAN that enables visitors to access the Internet without also giving them access to the corporate network. Green IEEE 802.3az energy-efficient Ethernet scales down power consumption during periods of low data activity, saving 50% energy. Cable length detection adjusts signal strength to the cable length, reducing power consumption on shorter cable runs. | |

Network Switch Buying Guide
Connect Multiple Devices to a Network and Route Data to Designated Devices
What is a network switch and what does it do?
A network switch connects devices to a local area network (LAN) and allows the devices to communicate over the network. For example, you can connect computers, printers and servers to the same network switch and route data between them. Unlike an Ethernet hub, which transmits the same data through every output, a network switch sends data only to the devices designated to receive it. This improves the efficiency and potential throughput of the network.
Are there different types of network switches?
There are two main types of network switches, unmanaged and managed. The essential difference is the capability to configure the operation of a managed switch to customize and optimize network traffic for specific applications.
Unmanaged Switches
- Offer plug-and-play functionality
- Switch operation cannot be modified
- CompSource offers desktop and rack-mount unmanaged switches
Managed Switches
- Provide the ability to manage, prioritize and monitor LAN traffic
- Offer one or more ways to modify switch operation
- CompSource offers smart managed switches that feature an RJ45 console port and command line interface (CLI)
Where do you place network switches?
Network switches are usually placed on a desk or table, mounted on a wall, or mounted in a rack. CompSource offers unmanaged desktop switches (with metal or plastic housing) and both unmanaged and managed rack-mount switches with metal housing and a built-in PDU (Gigabit Ethernet Switch PDU Combos).
What is a Gigabit Ethernet Switch PDU Combo?
CompSource offers an exclusive line of unmanaged and managed Gigabit Ethernet switches that have Power over Ethernet (PoE).
Factors to Consider
Does your application require a managed switch?
If your application involves controlling network traffic, you will need the features of a managed switch. The following are some examples of tasks that require a managed switch:
- Controlling access between departments within your LAN
- Running many bandwidth-intensive applications simultaneously
- Giving important data greater priority in your LAN
- Improving the performance of a busy network
- Implementing VoIP, wireless LANs or other advanced services
How many devices do you need to connect to your network?
Make sure you select a switch with enough Gigabit (10/100/1000 Mbps) Ethernet ports for the devices you want to connect to your network. If you think you'll add more devices in the future, choose a switch that will give your network room to grow.
Do you need to connect multiple network switches?
If you plan to connect multiple network switches, look for models with SFP uplink ports (also known as Mini-GBIC ports). SFP uplink ports are connection points for SFP (small form-factor pluggable) modules that allow the switch to uplink to other switches using optical fiber cabling.
Power over Ethernet (PoE) uses existing network cables to power connected devices, such as VoIP phones, wireless access points and surveillance cameras. If you need this functionality, look for a switch with Gigabit Ethernet ports that support PoE. Make sure the power per port (in watts) and the total power budget of the PoE ports meet the needs of your electronic devices.
CompSource will educate and help make this process enjoyable and easy.
Whether you're planning on using your network for basic home tasks or enterprise level security. You can tell our trained sales professionals your needs, and we'll make custom recommendations to suit your specifications and budget. Our reps have extensive knowledge and love to share. We educate, not sell, CompSource makes sure you buy what you need and not waste money on what you don't. As with every decision we never push, it's up to you when, and if you make a purchase.
CompSource has a great technical staff that can help with a solution for your exact needs.

Cant really say more than has already been said. Great staff fast delivery, best online experience i've ever had. I bought stuff even if i found a slightly better price, because i knew where i could get reliable courteous service. And if they treat international customers this well (considering i cant picket their offices) then i'm sure no one will be disappointed with their experience. Kudos to Jason lakes lakers aikes.... hell Jason at 101 thanks a lot really great service. tavin001More Reviews
